The HP480 is a combined Pt100 temperature and relative humidity probe designed specifically for dew point measurement in compressed air distribution systems. Equipped with a SICRAM module for plug-and-play instrument compatibility, it features a 15µ sintered AISI 316 stainless steel filter, a stainless steel measuring chamber, an air flow regulation valve, and three 1/4" quick couplings (Italian, German, and American standard) for tool-free installation without system shutdown. Operating range: -40...+60 °C, 0...100 %RH, 0...16 bar. Dew point accuracy: ±1 °C DP (0...+20 °C DP). Monitoring dew point in compressed air prevents pipe corrosion, ice formation, bacterial growth in medical systems, and ensures proper lubrication of pneumatic drives. Protection degree IP65. Cable length 2 m.

The probe can be installed in any position. The connection to the compressed air can be achieved with a threaded connection or with a quick connection.
The connection allows for quick installation and removal of the probe without stopping the system. There are 3 different couplings supplied: 1/4” Italian, German and American standard.
The probe is equipped with a filter made of sintered steel, stainless steel measuring chamber and control valve of the air flow. Suitable for measurement of compressed air with dew point up to class 3 according to standard ISO8573-1.
To connect with quick coupling, you can use one of the standard 1/4” couplings provided. Other couplings than those supplied can be used, provided that they have a G 1/4” thread on the side that fits into the probe.
For the connection by threaded coupling, the connection must have an external G 1/4” thread on the side which will be placed in the probe. The connection must be airtight. When installing or removing the probe, it is necessary to depressurize the system.
For direct connection of the probe, use a fitting with internal G 1/2” thread on the side which will be placed in the probe. The connection must be airtight. When installing or removing the model HP480, it is necessary to depressurize the system. Ensure that the probe does not obstruct the normal flow of air through the distribution line.
In all modes of installation, it is recommended that you place in the plant, upstream of the sensor, a safety valve to be closed manually in case of maintenance of the probe.
Periodically check the cleanliness of the sintered filter of the probe, in order to maintain optimum response characteristics of the probe. The filter can be washed with a detergent that leaves no traces.
